In this post, we'll talk about the many bearing types that are available, as well as their benefits and drawbacks. Furthermore, we'll describe how to choose the ideal bearing size for your requirements.

Bearing Types



There are many different kinds of bearings, each created to address particular demands and purposes. There are 4 primary categories of bearings:



  • ball bearings

  • roller bearings

  • needle bearings

  • thrust bearings


Ball bearings are the most common type of bearing and can be found in a wide range of machinery and equipment. The shaft is held in position by these bearings, which use tiny, hardened steel balls. Between two circular plates known as races are the balls. Another frequent type of bearing is the roller bearing, which substitutes cylindrical rollers for balls. Needle bearings are bearings that use small, sharp needles to keep the shaft in place. Thrust bearings are types of bearings that use flat plates known as races to hold a shaft in place.

The size of a bearing is determined by the inner diameter (ID) and the outer diameter (OD). The diameter (ID) of the bore, or the hole in the center of the bearing, is its measurement. The measurement of the outer race is called the OD. The width is a measurement of the bearing's width.

Consider the load, speed, and vibration that the bearing will experience while selecting a bearing. The load is the weight or force that the bearing will need to support. The speed is the rate at which the bearing will be spinning. The vibration indicates how much movement the bearing will undergo.

There are many different places to buy bearings. One choice is to get bearings from a neighborhood bearing supplier. A different choice is to buy bearings from a bearings-specific website online.Some websites that sell bearings also offer a web-based quoting system that can provide you with a quote for the bearings that you need.

There are many different types of bearings on the market, and each has pros and disadvantages of their own. Ball bearings, roller bearings, bearing housings, and bearing units are the four most typical types of bearings. Every kind of bearing has a distinct set of qualities that make it more or less appropriate for particular applications.

The most popular form of bearing and the one that is utilized in the most applications is the ball bearing. They usually consist of a set of balls that spin between inner and outer races and are constructed of steel or ceramic. Ball bearings are perfect for applications involving high speeds and/or loads since they are reasonably easy to use and long-lasting.

Although identical to ball bearings, roller bearings are made to support greater loads. They typically consist of a set of cylindrical rollers rotating between inner and outer races and are constructed of steel or brass. In applications where heavier weights are present but speeds are not as high, roller bearings work better than ball bearings but are less robust.

In addition to providing a means of mounting bearings onto a shaft or other support structure, bearing housings are enclosures that shield them from external pollutants. A range of sizes and shapes are available for bearing housings, which are commonly composed of cast iron or steel.

Bearing units are self-contained bearings that are pre-assembled and ready to be installed. Usually, a housing, a bearing, and a seal make up these devices. Bearing units are available in a variety of sizes and configurations, making them suitable for a wide range of applications.

In terms of rolling bearings, plain bearings, and products for linear motion, SKF is a global leader in design, development, manufacture, and marketing.


Ball Bearings:


The most popular type of bearing is a ball bearing. They are constructed from a set of balls, two metal rings known as the inner and outer races, and two metal rings. The bearing really rolls on the balls. The inner race is usually attached to the shaft that the bearing is supporting. Usually, the outer race is fastened to the housing.

Roller Bearings:


In contrast to ball bearings, which employ balls, roller bearings use cylinders. Roller bearings can support higher loads than ball bearings, but they are also more likely to fail under high loads.

Plain Bearings:



The simplest kind of bearings are plain bearings. Two metal surfaces that slide against one another are used to create them. To lessen wear and friction, plain bearings can be greased with oil or grease.

Considerations such as bearing types and sizes are crucial when choosing the best bearings for your application. Bearings come in a wide variety of forms, and each type has a distinct set of advantages and disadvantages that can be found on the market. If the wrong kind of bearing is chosen for your application, it may lead to greater wear and tear, decreased performance, or even early failure.

The first step in selecting the right bearings for your application is to identify the type of loads that will be applied to the bearings. Radial, thrust, and combined loads are the three main types of loads that bearings are intended to withstand. Whereas thrust loads are provided in a parallel direction, radial loads are applied perpendicular to the shaft. The terms "radial loads" and "thrust loads" are interchangeable terms.

Once you have identified the type of loads that will be applied to the bearings, you can narrow down your options by considering the size of the bearings. From small bearings that can sustain light weights to huge bearings that can support enormous loads, bearings come in a variety of sizes.The shaft's diameter and the amount of load that will be placed on the bearings will determine the size of bearings you require.

The sort of environment the bearings will operate in should be taken into account when choosing bearings for your application. Bearings that will be exposed to wet or corrosive environments will need to be made from materials that can resist rust and corrosion.Bearings that will be operating at high speeds will need to be designed for high speed operation.Furthermore, materials that can endure high temperatures must be used to create bearings that will be exposed to them.

There are many different types of bearings, each designed for specific applications and operating conditions. The three major groups are ball bearings, roller bearings, and sleeve bearings.


The most prevalent bearings are ball bearings, which can support both thrust and radial stresses.


They are produced in a range of shapes and sizes, such as:

-Angular contact
-Double row
-Four point
-Radial
-Self-aligning

The Blogspot following types of roller bearings are available:

-Cylindrical
-Ndeep groove
-Needle
-Spherical
-Tapered

Sleeve bearings, also known as bushings, are used in a wide variety of applications requiring rotation or linear motion.They come in a range of materials, including:

-Bronze
-Babbitt
-Plastic

The inner diameter (ID), outer diameter (OD), and width of a bearing are used to determine its size. Whereas the OD determines the size of the bearing's outer race, the ID is the parameter that determines the bore size of the bearing's inner race. The width is the dimension that determines the bearing's width.



  1. ball bearings - ID: 10 mm, OD: 30 mm, width: 9 mm

  2. roller bearings - ID: 20 mm, OD: 47 mm, width: 14 mm

  3. sleeve bearings - ID: 5 mm, OD: 10 mm, width: 4 mm



When choosing a bearing for a particular application, the ID, OD, and width of the bearing are all crucial considerations.

A ball bearing is a specific kind of rolling-element bearing that uses balls to keep the distance between the bearing races constant. A ball bearing's main functions are to support radial and axial loads and lessen rotational friction. It achieves this by using at least two races to contain the balls and transmit the loads through the balls.
In most applications, one race is stationary and the other is attached to the rotating assembly. Using ball bearings to support the rotating shafts of wheels was one of the first uses for them.
The invention of the ball bearing is attributed to Jules Suriray, a French bicycle mechanic, in 1869. He filed a patent in November of that year. Engineer Friedrich Fischer from Germany created the first industrial ball bearings in 1883.
